, CARRIAGE-LOCK FOR CALCULATING-MACHINES Specification of LettersPatent. P t t J ly 1 1921 Application filed February 7, 1920, Serial No.356,882. Renewed May 12, 1921. Serial No. 468,978:

To all whom it may concern:

Be it known that I, EDGAR E. PHINNEY, a citizen of the United States,resident of Vest Orange, in the county of Essex and State of New Jersey,have made a certain new and useful Invention in Carriage-Lock forCalculating-Machines; and I declare the following to be a full, clear,and exact description of the same, such as will enable others skilled inthe art to which it appertains to make and use the invention, referencebeing had to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

Figure 1 is sectional view of the invention, on the line 11, Fig. 2.

Fig. 2 is a front view, with parts broken away, the carriage being shownin normal position.

Fig. 3 is a view similar to the right-hand end of Fig. 1, the carriagebeing shown as raised.

Fig. 4 is a view similar to the left-hand end of Fig. 2, the carriagebeing shown as raisedl The invention has relation to means forpreventing displacement of the shiftable carriage of a calculatingmachine during a registering operation, being particularly applicable toa machine of the 1; shown in the reissue patents to Baldwin, No. 13,842.

The object of the invention is to provide a locking means of thischaracter which will render it impossible to operate the machine unlessthe carriage is roperly positioned, with the gears carried t ereby fullymeshed with the corresponding gears on the frame.

The invention consists in the novel construction and combinations ofparts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 1designates the frame of the machine, and 2 an endwiseshiftable carriage,pivoted upon said frame at 59, said carriage having mounted thereupon aseries of numeral or registering dials 13, each carrying a gear. Aseries of intermediate gears 12 ismounted upon frame 1, in position tomesh with the gears of the dials 13, these intermediate gears beingoperated by primary selecting elements 5, mounted on rotary shaft 4, andby carry teeth 7', mounted upon shaft 73, as described 0.- 13,841, and

hereinbe'fore-mentioned, the carriage being raised upon pivot 59 todisengage the respective gears, laterally shifted and allowed to seat inadjusted position through gravity. This is accomplished by means ofa-rotatable rod 61, having opposite crank arms 64, engaging seats of anelement of the carriage frame located opposite pivot 59. The engagementof the opposite arms 64 with the seats 65 will prevent endwi'se movementof the carriage, so long as it remains'seated in normal position.

The carriage positioning and locking means comprises a disk at, rigidlymounted upon an element of the operating means;

herein shown as the shaft.4 of the primary selecting elements. This diskis notched circumferentially at e, the lateral walls of the notch lyingnormally upon opposite sides of a beveled tooth or projection b ofa'lever c, pivoted to the frame at i and extending below shaft 4. Thefree end of lever c has pivoted thereto an extension arm a, terminatingat its upper end'in a hooked head a, normally en aging a horizontalledge or shoulder 71. o the carriage frame.

When the carriage is raised upon its pivot, lever c and its extensionarm a will be raised freely therewith, tooth b entering the notch ofdisk (I.

Upon rotation of the crank handle 3 in either direction, the rotativemovement of shaft 4 will bring a wall of notch e into e'nwise s iftingmovement of said carriage, to

bring the gears of the registering dials fully in mesh with the gears12. The peripheral face 9 of disk d will now be opposite tooth 6,thereby preventing the raisin of the lever and carriage until thecompletion of the registering operation, when .the notch 0 will againcome opposite tooth 6. Obviously, the registering movement cannot occurwhile the carriage is raised, as thetooth is held in the notch of diskd.

Provision is made for manually unlocking the carriage at any time, byallowing a pivotal movement of extension a upon lever 0, so that thehooked head a may be rasped and pulled out of .engagement with s oulderh of the carriage, against the tension of a spring f of said extension.

I claim:

1. In a calculating machine, a frame, an endwise-shiftable carriage,registering dials thereon, gears upon said dials, driving gears mountedon said frame, means for operating 7 said driving gears, and lockingmeans preventing movement of the operating means whenever the gears ofsaid dials are out of mesh with said driving gears.

2. In a calculating machine, a frame, an endwise-shiftable carriage,registering dials thereon, gears upon said dials, driving gears mountedon said frame, means for operating said driving gears, and meansactuated by the operating means for shifting said carriage endwise tobring the gears of said dials into mesh with said driving gears.

3. In a calculating machine, a frame, an endwise-shiftable pivotedcarriage, registering dials thereon, gears upon said dials, drivinggears mounted on said frame, 'means for operating said driving gears,and means actuated by the operating means for moving said carriage uponits pivot to bring the gears of said dials into mesh with said drivinggears.

4. In a calculating machine, 'a frame an endwise-shiftable carriage,registering thereon, gears upon said dials, driving gears mounted onsaid frame and meshing with the gears of said dials, means for operatingsaid drivin gears, means for disengaging said meshe gears and forshifting the carriage, and means actuated by the operating means forreengaging said, ars.

5. In a calculating mach1ne, a frame, an

- endwise-shiftable carriage, registering dials thereon, gears upon saiddials, driving gears mounted on said frame, means for operating saiddriving gears, and means for locking the carriage against movementduring the operation of said driving gears, said locking meanspreventing movement of the operating means whenever the ars of saiddials are out of mesh with said riving gears.
